It's coming from a lot of pro-Trump, ultra-right-wing haters who despise California because they know that it'll never "go red". Same with New York. Although, for some reason, they have extra hate for California. Especially SoCal & the Bay area.
I think it's comical how pissed off they get at the state & pretty much anyone from there.
I was on a Facebook group devoted to the Sedona area last night & there was an idiot who wrote the vilest things to me when I mentioned that I'm originally from New York & that Jana's from California. He was apoplectic about the fact that we moved to "his" state & that we're going to "flip" it blue. It was hysterical how upset he was. I'm surprised he didn't have a bloody aneurism as he was typing. Of course, I deliberately said things to further anger him but not until he got rude first. After that, I gave it to him both barrels.
